may have been monitored or recorded as:
i would like to quickly append a string to a variable.
open NEWFH, "> $filename.new" or die "new procmailrc err"; where $filename has /tmp/xyz
Anything really silly here??
Nothing I didnt do wrong at least a thousand times:
open NEWFH, "> $filename".".new" or die "new procmailrc err";
forgive me for being 'pedantic' but given the sequence
foreach my $filename (@list_of_file_names)
{
open(NEWFH, "> ${filename}.new" ) or die "new $filename err:$!";
....}
One has 'less ambiguity' using the curley braces around the variable name so that it will KNOW without a doubt that one really means that to be the variable should suffice - It really becomes important when you want to concatenate without things like a "." between tokens
foreach my $start (@entree) {
foreach my $phrase (@list_of_sillies) {
my $freak = "${start}Buzz${phrase}here";
rhetorical_devices($freak);
}
}
